What to enter
| Input | Meaning and units |
|---|---|
| Source charge (C) | Enter source charge in C; use the same basis as the other measurements. |
| Distance (m) | Enter distance in m; use the same basis as the other measurements. |
Understanding your result
Read Electric potential (V) in the units and model stated on this page. The formula potential=8.9875517923e9*q/r defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
